NON-SLIPPING ATTACHMENT FOR OVERSI-IOES.

Specification of Letters Patent.

Patented May 13, 1919.

Application led November 27, 1918. Serial No. 264,330.

To all whom it may concern:

Be it known that I, WILLIAM A. Mnvrz- Lorr, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Non-Slipping Attachments for Overshoes, of which the following is a specication.

My invention relates to means applicable to rubber overshoes whereby persons wearing the same are prevented from slipping when walking on ice during the winter season. The invention may be otherwise termed an improvement in non-slippable ice-treading overshoes.

The object of the invention is to provide a heel attachment for overshoes which may be applied to new overshoes as well as those which are partially worn and have become more liable to slip on ice because of the smooth surface of the rubber at the heel due to artial wear.

he accompanying drawings illustrate the device and referring thereto in general terms Figure l is a bottom plan view of the heel portion of a rubber overshoe having my nonslippable attachment applied; Fig. 2 is a longitudinal sectional view of the heel portion of a rubber having my attachment applied; and Fig. 3 is a cross sectional view of the heel of a rubber overshoe having my attachment applied.

The device is intended to prevent slipping while walking on ice during the winter months and it may be attached to the heels of new overshoes as well as old ones. It is applicable to the heel of the overshoe as shown in the drawings. Referring to these in more particular terms 1 designates the heel or back portion of a rubber overshoe having the usual thickened tread portion 2. It is to this part of the overshoe the device is attachable. It is there shown to consist of a relatively thin metallic plate 4c which lies on the inside of the tread portion 2 of the heel, and a metallic casting 3 which fits against the outer side of the heel tread. These two plates are shaped to the heel and the inner plate 4 is essentially thinner than the outer one in order that the heel of the shoe shall not be elevated too high from the heel of the overshoe when the latter is being worn. These two plates, 3 and 4f, are attached to the heel tread 2 by means of rivets 5 which pass through apertures in the heel tread 2 and hold the plates firmly to the inner and outer sides of the heel tread 2. The cast metal plate 3 is provided with two or more pointed steel spurs 7 which are riveted thereto through suitable openings in said plate. These pointed spurs engage the ice when walking thereover and prevent slipping thereon as is obviously apparent. The spurs 7 are formed of hard steel so that their points will not become blunt and thereby retard their efliciency. At the forward end of the plate 3 a lug or projection 6 is cast the purpose of which is to prevent the forward part of the heel from giving down too far when the overshoe bends at a point forward of the heel when the wearer thereof is walking thereby relieving the strain on the de-- vice.

I-Iaving described m invention, I claim:

l. An overshoe attac ment comprising in combination therewith, an inner plate, and an outer plate attachable to each other through the tread portion of the heel of the overshoe and held firmly thereagainst, the outer plate having ice-penetrating spurs thereon, and a lug on the forward part thereof, substantially as specified.

2. The combination with a rubber overshoe, of a non-slippable attachment therefor comprising an inner relatively thin metallic plate engaging the inner side of the heel of the overshoe, a metallic plate engaging the outer side of said heel, the two plates being i'irml united by means passing through the said eel, ice spurs fixed to the rearward part of said outer plate, and a lug united to the forward part thereof, substantially as described.

In testimony whereof I afliX my signature.

WILLIAM A. MINTZLOFF.
